UNITED STATES I ROBERT C. SOHENOK, OF DAYTON, OHIO.

BRAKE-LEVER.

SPECIFICATION forming part of Letters Patent No. 636,070, dated October31, 1899. Application filed May 15, 1899- Serial No. 716,799. (NomodeL)To (0Z4 w/wm, it may concern.-

Be it known that 1, ROBERT C. SoHENoK, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Brake-Levers, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings, forming part of this specification.

My invention relates to the construction of brake-levers forrailway-cars, wherein the great desideratum is lightness combined withstrength; and it has for its object the production of such levers ofmalleable iron, whereby the purpose above stated is accomplished.

The novelty of my invention consists in constructing the levers ofmalleable iron,with a comparatively thin central web with peripheralflanges surrounding it and projecting from its edges on both sides andtransverse strengthening-ribs between said flanges on both sides of theweb, which ribs on the opposite sides of the webs run in oppositedirections, so as to bisect each other, all as will be hereinafter morefully set forth, and specifically pointed out in the claim.

In the accompanying drawings, Figure 1 is a side elevation of abrake-lever embodying my invention. Fig. 2 is a sectional plan view ofthe same on the dotted line at m of Fig. 1. Fig. 3 is a side elevationof a brake-lever embodying my invention in a modified form.

The same letters of reference are used to indicate identical parts inall the figures.

The brake lever herein represented has a comparatively thin central webA, surrounding which at its periphery and projecting from both sides atright angles is a flange a, merging at one end of the lever into a solidportion 1), having a perforation c, and at its opposite end into a solidportion d, having a perforation 6, these two perforations serving as thepivotal connections for the operatingrods. Between these two endportions 1) 01 there is another solid portion f, having a centralperforation g to serve as the bearing for the fulcrum pivot of thelever. This construction is common to the three figures shown.

In Figs. 1 and 2, h are transverse ribs on each side of the web A,extending from the solid portions 1) to the solid portions f between theflanges a and bisecting each otheron the opposite sides of the web, asshown by the dotted lines in Fig. 1. Between the solid portions f and bthere are a series of transverse ribs t' between the flanges and on bothsides of the web, which bisect each other on opposite sides, as seen bythe dotted line in Fig. 1. The majority of these biseetions occur on thedotted line 0000, which is the central line of the lever, and thus thelever is strength ened not only by the truss formation of the ribs, butby this increase of metal afforded by the presence of the ribs, as willbe readily understood.-

In Fig. 3 the only variation is in having the ribs 2 on each side of theweb run in azigzag manner from one flange to the other, as shown. Thebisection of the ribs on both sides of the web occurs on the middle lineof the lever, as seen by the dotted lines.

I found from actual experience that in constructin g levers of thischaracter of malleable iron in the manner described I am enabled toreduce their weight very materially and ohtain great strength, bothagainst fiexure and breakage. The ribs arranged transversely,

as I have described, act as struts or ties to brace the whole structureand give it great rigidity.

Having thus fully described my invention, I claim As a new article ofmanufacture, a brakelever constructed of malleable iron having acentralweb with thickened perforated end and intermediate portions to formpivotal bearings, and with peripheral flanges on both sides of theweband transverse ribs on both sides of the web extending between theflanges, and arranged with their directions of length to intersect eachother on opposite sides, substantially as described.
